Can Science Find the Truths of Morality?

Sam Harris thinks it can. In this TED talk, he argues that (1) science is tasked with tracking down truth, (2) there are such things as moral truths, so (3) science can find moral truths. Given the way he frames “truth” (watch the video to see, as it’s both interesting and more complex than I want to summarize here), I accept (2) but tentatively reject (1), meaning I have to abandon (3).
